bauhaus design principles

at the implementation level! All interactions we define use the base class. What if a subclass cannot completely replace the base class during implementation? Is there a problem with all the interactive contracts? A subclass derived from a base class should support all actions of the base class. The base class must be replaced by the subclass. This is the LSP principle. We can see that the responsibility and interaction of objects are defined as early as possible. In this process, we did not co

. 05 pay attention to the website running status during website upgrade. Hosts with good performance may run slowly as the number of visitors increases. However, if you do not want to lose visitors, you must carefully plan your Upgrade Plan. 06 adhere to the basic principles even if you do not understand the HTML language, you only need to buy a copyright WYSIWYG web design tool, such as Adobe pagemill or M

Seven Principles of Software Design The general principles of design patterns are as follows: 1.Open-closed principle ):A software entity should be responsible for extended development and should be closed for modifications. when designing another module, the module should be extended without being modified. in other

1. Single Responsibility Principle Whether in design, interface, or method, a single responsibility is everywhere. A single responsibility is defined as the cause of system changes. When defining classes, interfaces, and methods. After the definition is complete, think about it again. There is no more motivation to change this class, interface, and method. If the answer is yes, the defined class, interface, and method are more than one responsibility.

General principles of design pattern adherence:1. Open-Close principle (open-closed Principle, OCP): a software entity should be developed for expansion and closed for modifications. The point is that when designing a module, the module should be extended without being modified. In other words, It should be possible to change the behavior of the module without having to modify the source code, and to extend

I recently encountered a problem with the design principles of OOD during the written examination. From http://www.cnblogs.com/xwang/archive/2009/01/13/1374652.html Five Principles of OOD: (1): SRP, single responsibility principle (only Buddha should assume the responsibility to publish xuanmiao secrets ...) A class should have only one reason for change. Because

Learning design mode is the beginning of learning six principles, because the six principles of the emergence of the final object-oriented TV model competition really fierce ah. Now let's take a look at our six principles. Single Responsibility Principle (SRP):From the side dishes and Big bird shooting UFO to talk abou

During software design, the degree of detail of analysis and design, as well as design deficiencies and transitional design problems are usually encountered. Generally, the purpose of design is to grasp the degree of design, avoid

Before we learn the seven principles of object-oriented design, we should have a good understanding of basic encapsulation, inheritance and polymorphism, as well as the ability to encode abstract classes and interfaces, because design patterns are the integrated application of the above knowledge points.In addition, before contacting the specific

the programmer should have the-solid principle of artistic temperament. S.O.L.I.D is the acronym for several important coding principles (programming Priciple) in object-oriented design and programming (Oodoop). SRP The single Responsibility Principle Single Responsibility Principle Ocp The Open Closed Principle Open Closure principle Lsp Th
